The coordinates of the three points are: A: (X, Y, Z) = (0.0, 10 in, 0.0) B: (X, Y, Z) = (0.0, 3 in, 12 in) C: (X, Y, Z) = (8 in, 4 in , 5 in) Find the following. Express your result in terms of unit component vectors: " a) FAC (the positioh vector from A to C) b) the projection of FAC onto the line defined by points A and B c) If a force F = (16N)}t is applied at point A, resolve this force into components parallel and perpendicular to the line defined by points A and B. » ’5: 795“ my“, 5°12 \ 2' . ‘1‘ Y K x‘ V [(7 M52 +(IZM> , lQK r (salcfcfjsz 3f 8%1‘9' ~ gpmjut 5%— "#3 grad“ In {Lib 33A [W‘ . p0 Uk 1 £6 m[¢rf' ‘9 UL / w—A ...\ ‘w‘ , g 2 g ":7.
